ok I accept a trouble yesterday I pulled a new net cable from my modem to my office (true cat 7)

but the problem is that I still receive 100mbps on my pc,

but if I plug the same cable into my laptop I get 250mbps download (exactly what my subscription says)

I also removed and reinstalled the drivers from Realtek, I likewise set speed and duplex to ane gigabit, and I started in windows safe mode to see if I can reach those speeds there but unfortunately, I only got 100mbps aslo in there

There are not many things that can cause this since it is not really a software affair unless you strength it to 100mbps with software. This is done mostly at a very low hardware level and then the problems always tends to be physical issues.

You either take something wrong with the ports on either cease or you have a bad cable. Bad ports yous can't ready anyhow but lucky it is very rare. It would exist nice if a bad cable would just not work but in almost the time they work randomly quondam on other machines and sometime just plugging and replugging them fixes information technology for a while .

It is normally some consequence with the finish of the cablevision existence merely slightly damaged or loose in some way.

In that location are false cables that are not pure copper or have pocket-sized wires that you get strange results considering they do not come across the standards for ethernet cables.

Check to be certain "Auto Disable Gigabit" isn't enabled in the drivers.

I don't know why Realtek even put that setting in there, simply apparently it's to save less than a watt of energy.

Check to be sure "Car Disable Gigabit" isn't enabled in the drivers.

I don't know why Realtek even put that setting in there, but apparently it's to salve less than a watt of energy.

I merely looked and I see that it is just switched off, I detect it weird that i have that trouble, i had a look online and looks like im the but one with this problem

It could be that one of the conductors on the cease of that cable is not making a good connection with the jack, because only half of the wires are needed for 10/100 performance. So the easiest thing to try is a new cablevision, or even reversing the one yous've got (as information technology clearly works at gigabit).

Or else the NIC could just be bad!

There are not many things that can cause this since it is not actually a software thing unless you force it to 100mbps with software. This is done more often than not at a very low hardware level so the problems ever tends to exist physical bug.

You either have something incorrect with the ports on either end or you have a bad cable. Bad ports you can't fix anyway but lucky information technology is very rare. It would be nice if a bad cable would but not work but in well-nigh the time they work randomly sometime on other machines and sometime just plugging and replugging them fixes information technology for a while .

It is normally some issue with the end of the cablevision being just slightly damaged or loose in some way.

There are fake cables that are not pure copper or have small wires that you become foreign results because they practise not meet the standards for ethernet cables.

I have changed the cable and nix still 100mbps, I did likewise cleaned the port on my pc, there was a little bit of dust merely that wasn't the problem either

There are not many things that can cause this since it is non actually a software thing unless you force information technology to 100mbps with software. This is done mostly at a very low hardware level so the problems always tends to exist concrete issues.

You either have something wrong with the ports on either end or you accept a bad cable. Bad ports you tin can't fix anyhow but lucky it is very rare. It would exist dainty if a bad cable would just not work but in most the time they piece of work randomly old on other machines and sometime just plugging and replugging them fixes it for a while .

Information technology is normally some event with the finish of the cable being just slightly damaged or loose in some fashion.

There are simulated cables that are not pure copper or accept pocket-size wires that y'all get strange results because they do non meet the standards for ethernet cables.

I take an electrical background, and I am 100% sure that it is properly connected. and straight but to my standers
and I have a true cat 7 SFTP 23awg, and believe me if it wasn't a cat7 I really didn't pull it up to my office

and it must be a bad port why tin can my laptop with exactly the aforementioned cable and port merely 250mbps?

If you have wall jacks just remove and re punch the connectors it is adequately easy to try.

If you lot really recollect information technology is a bad port in your pc yous have few choice. You can non fix it so you must purchase either a add in pcie board or use a USB port.

Am I missing something? All OP needs is a cable and directly attaching the laptop to the PC to examination if it lights up at 1Gbit.

They don't fifty-fifty need to prepare a fixed IPv4 address, just to look at the blinky lights

stock-still the problem, after some excavation when I saw that the computer and laptop had a gigabyte connectedness, I started looking in the router itself, did a new software install. and low and behold my computer is getting the 250mbps like information technology should
